Listener output

[Barry Denton]

I have a Listener added to a button as so :-

button.addListener(DWT.Selection, new class Listener {
        void handleEvent(Event event) {
            itemWords [5] = "item has changed " ;//~ System.currentTimeMillis();
            minitable.clear(5);  }  }); 

When pressed the button outputs this:-

Event {missing or misplaced '}'}Event {type=13 Button {Change item} time=1679601378 data={null} x=0 y=0 width=0 height=0 detail=0}
.
Now all is as it should be except for the  {missing or misplaced '}'}

1/ Can anybody see why I get this message? 

Also "System.currentTimeMillis()"is a C style request .

2/  is there a similar request in D for a Linux machine?
